Senior Shopify Developer

We’re looking for a Senior Shopify Developer with a strong front-end focus to take ownership of our Shopify ecosystem and drive it forward with confidence and autonomy. This role is ideal for someone who excels at building high-performance, conversion-focused storefronts, leading front-end Shopify development, and turning commercial goals into polished, scalable e-commerce experiences. While the role is primarily front-end, you’ll also need solid back-end and integration experience to ensure our platforms are robust, well-connected, and future-proof. You’ll have the freedom to move projects forward independently, with the backing and support of a collaborative in-house team. You’ll work closely with commercial stakeholders, marketing, product, and design to ensure our Shopify platforms are fast, scalable, conversion-focused, and aligned with brand and business objectives. This is a hybrid role, with Thursdays based in our Stockport office and flexibility the rest of the week.
